Translation consists of reproducing in the receptor language the closest natural equivalence of the source language message, first in terms of meaning and secondly in terms of style. (Nida and Taber, 1969:12)

Translation is the rendering of a source language (SL) text into the target language (TL) so as to ensure that (1) the surface meaning of the two will be approximately similar and (2) the structure of the SL will be preserved as closely as possible, but not so closely that the TL structures will be seriously distorted (Mc.Guire, 1980:2)

Roger T. Bell (1993:5), translating the definition of translation according to Dubois, states that Translation is the expression in another language (or target language) of what has been expressed in another, source language, preserving semantic and stylistic equivalences.

Translation is the general term referring to the transfer of thoughts and ideas from one language (source) to another (target), whether the languages are in written or oral form; whether the languages have established orthographies or do not have such standardization or whether one or both languages is based on signs, as with sign languages of the deaf (Brislin, 1976)

Translation is a transfer process which aims at the transformation of a written SL text into an optimally equivalent TL text, and which requires the syntactic, the systematic and the pragmatic understanding and analytical processing of the SL (Wilss and Noss, 1982).
